Pros: very secure fit, excellent sound, with wide bass extension without mudding the higher frequencies, solid carrying case, excellent microphone
Cons: can get uncomfortable after a couple of hours, not overly refined sound, cable sticks to itself (not tangle proof), microphone placement too low
Got this earphones for the sole purpose of working out/biking. Tested out multiple sports headsets (similarly priced), from sennheiser and bose. They tend to sound better, especially than the adidas sennheiser which sound pretty bad for the money. Great bass and clear mids and highs (considering it is bass-centric).
It is not neutral by any stretch, but you have to remember they are made for sports and wokring out mostly, so they are perfectly tuned for dyamic songs, like hip hop and electronic music, which is what most people listen to when working out (hence the name, Sonic Fuel). For these genres, they work PERFECTLY.
The in line mic has a analog volume control button, which is good since you will be able to modify the volume regardless what brand your phone is. The microphone is also very good, people on the other side of the line heard me clear.
The downsides are, in my opinion, the cables which have a tendency to stick to each other, making them non tangle free. The volume/microphone module is placed rather slow, so if you wear them under your shirt when working out it's kinda hard to take calls. Also, it would have been a big plus if they were at least sweat proof.
However they deserve a 5 star rating in my opinion because for what they are made, active wear, they are incredible stable in your ear, and are almost flawlessly tuned for the kind of music one listens to while working out.
